Abstract

Investigating the spatial-temporal variation characteristics of vegetation light-use efficiency on the Qinghai-Xizang Plateau has important ecological value and practical significance for determining the carbon sink and future function maintenance of terrestrial ecosystems. This study was conducted to explore the interannual dynamic variation characteristics of vegetation light-use efficiency on the Qinghai-Xizang Plateau and its relationship with temperature, rainfall, VPD, and solar radiation using GLASS data and climate data from 1982 to 2018 and trend analysis and partial correlation analysis methods. Results showed that (1) From 1982 to 2018, the LUE of the Qinghai-Xizang Plateau vegetation ecosystem generally exhibited a significant linear growth trend, with a growth rate of 3.16×10-3 g C·MJ-1·a-1. (2) The spatial distribution of LUE in the Qinghai-Xizang Plateau vegetation ecosystem had strong spatial heterogeneity, exhibiting an increasing spatial trend from west to east. The trend analysis revealed an obvious interannual growth trend of LUE in the central and northeastern regions. (3) Temperature was more closely related to interannual changes in the LUE of vegetation than factors such as precipitation and VPD. This study provides a basis for revealing the response of the Qinghai-Xizang Plateau vegetation ecosystem to climate change.
